detachable antislip heel plate which may.

be readily applied to or removed from an 10 ordinary street shoe, and which when in plied position will effectively prevent slip- F Further objects of the invention are to provide an antislip device of simple, practical construction, which will he rugged, du-

rahle and inconspicuous in use, and which is well suited to the requirements of economical manufacture.

With the above noted and other objects in W view, the invention consists in certain novel features of construction and combinations and. arrangements oi parts, as will be more fully hereinafter set forth and pointed out in the claim. The invention may he more fully 25 understood. "from the following description in connection with the accompanying drawings, wherein ig. 1 is a View in side elevation showing my improved antislip heel in applied po- 30 sition.

Fig. 2 is an enlarged perspective view of the device removed from a shoe.

Fig. 3 is a sectional detail on the line 3 -3 of Fig. 2.

In the drawings I have used the reference character to designate a shoe provided with the usual heel portion 1.1. The device of the present invention is in the nature of a flat metallic plate 12 conform- 49 mg to the under 'face of the shoe heel 11, and carrying a plurality of depending peripheral spurs or teeth 13 adapted to dig into the ice and prevent -a wearer of the plates from slipping". The plate is preferably made of steel or of some material which will offer rugged teeth at 13 adapted to sustain the weight of a wearer without bending. By providing a number of such teeth the weight will be fairly evenly distributed over them, and the teeth may he of compare tively'small size, and still efficiently serve their-purpose without bending.

A number of expcdients mightbe resorted to for quickly and securely attaching the heel plate to a shoe. The attaching means which have shown is subject to a wide variety of variations, but has proven rather eflicient inasmuch as itnot only permits the heel plate to, he quickly attached and removed, but assures lirrn attachment and permits the plate with its attaching device to be folded into a small compass when removed.

Slotted ears id proiecting outwardly from the plate and integral with the plate receive the looped intermediate portions 15 of metallic straps 16, the loops and the slotted ears forming a pivoted connection. Preferably one metal strap is attached at the rear of the heel plate and two other straps are attached adjacent the forward corners of the plate The free ends oi: the strap are spread apart to receive a U-shaped leather strap 17, the flexible leather strap being secured between the upper ends of the metallic straps by rivets 18 or similar securing devices.

The two metallic straps at the forward end oi? the heel plate also receive and secure foot embracing strap elements 19 and 20 one of which carries a buckle 21, and the other of which is formed with a series of holes 22 adapted for coaction with the tongue 23 of the buckle.

The construction which involves pivoting of the metallic straps 16 of the heel plate I is not only automatically self adjusting to various sized heels within a certain range of sizes, but also permits the metallic straps to be folded inwardly upon the heel plate and the detachable heel structure to be stored or carried in a relatively small space when metal plate conforming approximately to steam the shape of the under mean shoe hee1, lying in the plane of the plate and being eeid piate being provided at its edges with s otted for the reception of securing straps, e pinrelity 0f extensions, certain of said' metal straps .includin 'loop'ed intermediate 10 extensions being pointed and -turned down portions accommodate in the slots and shoe L f i 'gizrovide'e seriesof approximately equL- engaging straps retained between the free klistantly s aced depending spurs; alt the ends of the metallic straps.
